AN ODE.

Applicatibnflledlovember 29,1927. Serial No. 236,562.

This invention relates to anodes which are particularly suited for useinelectroplating objects of varying-lengths such as, for instance, lampposts, pipe, etc, 5 The anodes each consist of a rod-of inert conductivematerial carrying a body; of the anodic metal. The rod is provided witha hook at one end and an eyelet at the other end, both of which projectbeyondthe main .10 body of anodic metal. Any desired number of theanodes may be hooked together to correspond to the length of the objectto be plated by inserting the hook of one anode into the eyelet ofanother. The anodes may be made in varying lengths. Preferably the bodof anodic metal comprises longitudinal ro ections extending partlyaround'the eyeet'. These projections are placed in sucha way as not tointerfere with the hooking of one anode with another. v

The accompanying drawings illustrate one type of construction of theanodes inaccord= ance with our invention.

Fig. 1 is a front elevation of the anode; Fig. 2 is a top plan view;Fig. 3 is a bottom plan view and Fig. 4 is a side elevation of the anodeshown in Fig. 1. v

. The invention is particularly designed and adapted for use inconnection with cadmium or Z1110 plating anodes comprising a steel rodas the inert conductive material and cadium or zinc as the anodic metaland will be de- :7

scribed and illustrated such an anode.

In the drawings, A. is a steel core of square cross-section, the upperend of which is formed into the eyelet G and the lower'end into thehookE. Around this core is cast the body B of anodic metal, specificallycadmium. The projections D from the main in connection with body Bextend'partly around the eyelet. The 1 projections D preferably areformed as illus-j trated leaving? only a groove in the anodic t5 metaltransverse to the plane of the eyelet so that two anodes may be hookedtogether. I y

The steel core A is shown of square crosssection. but 'ob'viousl itmaybe round or of any other form.' A so, the outer. surface of the castanodic metal may be round'orof any oltlher desired form instead ofhexagonal as S 0WD.

gradually eaten away and the anode will .--sooner or.later break,whereas anodes made .the 00k and eyelet. Y

The advantage of these anodes is that they may be very easily hookedtogether toproduce an anode of any desired length. The weight of theanodic metal is carried entirely bythe inert and relatively strongcore... In anodes made entirely of anodic metal without a core of inertmetal, the anodic metal is 1n accordance with this invention will not.It has been found that if the steelcore is first electroplated"with'cadmium, the cad-. mium body may becast onto the core much moreintimately than if the core is'not electroplated. The breaking oif ofthe anodic V metal from the core during electrolysis is thus prevented.i

Anodes of the typevdescribed and illustrated have been made of cadmiumcast onto a steel core both with and without an'inte'rmediate coating ofelectroplated cadmium and have been found'to be of particular value forelectroplating objects of varying lengths. However, the invention is notlimited to cadmium anodes comprising a steel core excepting as may berequired. by the terms of the appendei i claims. Many shapes and sizesof the core of inert metal, the hook, eyelet, lugs and cast metal may bedesigned without departure from the invention. 1 4 I We claim I 1. Ananode for use inelectroplating, comprising a coreof inertconductivematerial which is formed into a hook at one end and-an Ieyelet at the other end,,said. core having a bod of anodic metal castaround it between v i 2.
